1README:
2  This file should be located at the top of the OpenJDK Mercurial root
3  repository. This root repository will include a "make" directory,
4  and a Makefile for building the entire OpenJDK.
5  A full OpenJDK repository set (forest) should also include the following
6  6 nested repositories:
7    "jdk", "hotspot", "langtools", "corba", "jaxws"  and "jaxp".
8  There are also several source downloads for the jax* repositories that
9  will be needed.
10
11  This one root repository can be obtained with something like:
12    hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
13  To make sure you have all the nested repositories, you can run:
14    cd openjdk7 && sh ./get_source.sh
15  (This is identical to using the Mercurial Forest Extension command 
16   'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
17  People unfamiliar with Mercurial should read the first few chapters of
18  the Mercurial book: http://hgbook.red-bean.com/read/
19
20  See http://openjdk.java.net/ for more information about the OpenJDK.

22Simple Build Instructions:
23  
24  0. Get the necessary system software/packages installed on your system, see
25     http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html
26
27  1. If you don't have a jdk6 installed, download and install a JDK 6 from
28     http://java.sun.com/javase/downloads/index.jsp
29     Set the environment variable ALT_BOOTDIR to the location of JDK 6.
30
31  2. Check the sanity of doing a build with your current system:
32       gnumake sanity
33     See README-builds.html if you run into problems.
34  
35  3. Do a complete build of the OpenJDK:
36       gnumake all
37     The resulting JDK image should be found in build/*/j2sdk-image
38
39where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and
40/usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
